lasting shoes and particularly .to machines of the type known as bed lasting machines in which a last, usually in inverted position,'is rested upon-a supportwhile the to the last.

upper materials are worked into lasted position at one or both ends of the shoe by end lasting devices or end lasting mechanisms. 1 i

For the best-results the end lasting mechanisms should face squarely toward the end portions of. the last to be acted upon or in the direction of the median line of the adi'acent end ortion of the last. These end asting mec anisms'used at the heel usually include a heel band which is depended u on to clamp the up er materialsabout the eel portion of the astand especially to force the end portions of the heel stifi'ener up These mechanisms also generally include, both at the heel and the toe, :wiper' plates which areemployed for wiping the upper over' the last into .position to be secured. In lasting welt shoes it is important that the toe lasting plates fit overthe last so that they will force the u per firmly u against the lip or shoulder o the inner so e to which the upper is to bepermanently secured by a subsequent'operation.

The lasts in general useat-the presenttime are formed with more fullness at the outer side of the, forepartand the heel art than at the inner side. Theexcess of ull- Kness on one side of the last as compared with the other side, which is commonly called the swing of \the last, is formed on the left side of a left last and on the right side .of a .right last. Therefore end lasting devices which are properly arran ed in accordance with the-swing'o'f a right ast on the hollow side 0 I to clamp the heel stiffener at the full side and the hollow side of the heel, and to force the'upper against the lip of the innersole at the-full side and the relatively straight side of the toe, will not be roperly arranged for the corresponding 1e t last. The heel band will not clamp the counter against the hollow side 'of the left last nor Wlll the toe wiper plates force the upper up to the lip of the innersole on the relatively straight side of the forepart without overriding and breaking down the lip on the full side. Another diflicult-y is found with the wiper plates at the heel, which in order tO'WlPG the upper over into os1tion to be tacked the heel have to be forced over beyond the nailing line on the full side. This makes it necessary forthe operator, after tacking the heel seat at the hollow side of. the last, to stop and back the wipers off from the full side before he can tack that side.

An object of the present invention is to provide a lasting machine of improved connisms shall be arranged for relative movement to enable them to face squarely toward and act properly upon the heel and toe-portions ofboth right and left crooked asts.

I have discovered that a machine can be adapted to act properly upon the heel and toe of both a right and a left crooked last by moving only one of theend lasting mechanis'ms provided the movementtakes place about a suitably located center. This center I have ascertained may be found at or near the point of intersection of the median lines of the forepart and heel part of the last.

These median lines (running from the rear end of the last forwardly midway between the sides of vthe-heel and from the forward end of the last rearwardly midway between the'sides of the toe) intersect in lasts now" in eneral'use at or near the rear part of the bal or the forward part of the shank. In.

a left last. the median line of the heel partextends obliquely toward one side of the last with relation to the median line of the forepartfrom the point of intersection of the two, lineswhile in a right shoe the median of a right or a line of the heel part extends obliquely toward the other side of the last from this point. Therefore by moving the heel lasting mechanism laterally about this point as a center, in one direction for a left last and in the other direction for a right last, said mechanism may be positioned 'properly for both a right and a left last, or a pair of crooked lasts. the end lasting mechanism should be moved about a center located approximately at the point of intersection of these median lines it may be that some of the advantages of the invention might be secured if the center of movement were otherwise located and the invention includes in its, broadest aspect a movement about a center so located that the end lasting mechanism may be positioned to act uniformly along the end part of the last in the direction of the median line of such part, irrespective of the swing or angular relation of the median lines of the fore part and the heel part of the last.

A very important feature of the present invention consists in an end-lasting mechanism, or other mechanism adapted to act .upon the end portion of a last, which is constructed and arranged to move laterally of the last about a center located under the last at a substantial distance from the ends of the last and preferably at or near the point of intersection of the median lines of the heel part and the fore part of the last. If the heel-lasting mechamsm be arranged for example, for movement about a center so located the toe-lasting mechanism may be stationary and arranged to facelsquarely toward the rear or, in other words, have its middle line in the middle line of the machine. The last, whether for a rlght or a left shoe will then be positioned with the median line of its toe portion in the middle line of the machine and the heel-lasting mechanism will be moved laterally about the point of intersection of the median line of the toe part and the heel part toward one side for a ri ht last and toward the other side for a le last Such an embodiment of the invention is shown in the drawings.

Preferably and in accordance with a further feature of the invention a rest for the heel end of the last will be arran ed for movement about a similarly locate center to adapt it to 've support to the heel part iift croo ed lastthe fore-part of which may be sustained in a fixed h tion. As shown, the heel support an heel-lastin mechanism are 0 erativelyconnected an move together a out the same center. In such movement of the heel support, however, the shoe actually pivots about a point at or near the toe end of the last where it is more or less confinedbetween the usual toe wipers and is sustained upon a toe rest which is preferably capable of move- While for the best results ment transversely of the machine to accomany the shoe in its lateral movement as will e later explained.

It will therefore be understood that a further feature of this invention is found in the provision for differential adjustment of the last and an end lasting mechanism, as for example, of the heel lasting mechanism about the pivot at the intersection of the described median lines and of the last simultaneously about the more remote center at or near its toe end. As herein employed this differential adjustment serves to move the heel lastin mechanism in the arc of a smaller circlet an that in which the heel end of the last is moved and thereby to set said lasting mechanism into'symmetrieal relation to the median line of the heel portion of a crooked 'last.

A further feature of the invention consists in novel means for limiting the transverse movement of the heel-lasting mechanism. This means consists in limiting devices which are adjustable together toward and from the middle of the machine and in the illustrated construction they determine 7 the extentofv movement of both the heel support and the heel-lasting mechanism.

Another feature of the invention is found in means for automatically locking the laterally movable parts at the limits of their movements. As shown, this means comprises a device movable with the laterally movable parts and arranged to coiiperate with the limiting device toward which they are moved in any position of said limiting devices.

One advantage of this invention is found in the fact that the lasting mechanisms are or may be maintained in their laterally adjusted relations to the last durin the lastmg operation. The heel band 0 the heellasting mechanism will thus act with certainty to clam the upper and heel stifl'ener against the ho low side of the last as well as a ainstthe full side, while the heel wi er p ates will overlie the heel seat the same istance on both sides so that the operator can tack all the way around the heel seat with- 'Itis sometimes found that an irregularity exists in a shoe which makes it desirable to adjust the toe-lasting mechanism laterally.

For example, the lip on the innersole may be formed farther from-the edge of one side of. the innersole than from the other side in a particular case or in successive innersoles.

In accordance with another feature of this invention provision is made for adjusting the toe-lasting mechanism laterally after the shoe has been clam ed in the machine or before the shoe is acked, as may from the center of-movement of the heellasting mechanism and which is herein shown as located for convenience under the toe-lasting mechanism, 'but near to the toe of, the last. Manually operated devices in the form of a screw and rack are provided by which the ad'ustment of the toe-lastin mechanism can e effected at any desire time-and the mechanism maintained in its adjusted position.

Another feature of the invention is'.concerned with the construction and arrangement of the end-lasting mechanism and its actuatin means. This is shown in connection wit a heel-lasting mechanism which 7 includes a band or clamp 'to embrace the heel portion of the shoe and clamp the upper materials to the side faces of the heel portion of the last, and also devices such as wiper plates for forcing the marginal ortions of the upper over the last bottom into position to be secured to the innersole. The

eel band-is normally open to its full width, as are also the wi er plates in order that the machine may e ready to receive the largest last for which it is adapted. In the machine shown the last is jacked or adjusted and fastened in position to be operated upon by lifting it to an appropriate level and then closlng the heel band about the heel end of the last in the usual way. In accordance with this feature of the invention, the

wiper plates are operatively connected with the heel band or its actuating mechanism so as to be automatically advanced from their open position when the heel band is closed. Preferably the wiper plates are also -con-; nected with a hand lever or other operating member by which they may be iven movements independently of the ban and in the illustrated embodiment of theinvention the plates are automatically moved up w to or slightly over the edge of the shoe and there- Y after are actuated by the independent operating member to overwork the upper as, in the judgment of the operator, the conditions presented by each shoe may require. One advantage of thus automatically advancing the wipers is that the operator is relieved of a portion of the movement other wise required in subsequently manipulating them. The operating member is herein shown as a hand lever which, by the auto;

' erable pressure upon the rest.

maticall effected movement of the wipers,

is broug t from a position where it is out o osition feature of the invention two positioning means are employed which are connected 0 eratively with the jacking means alread escribed for positioning the toe and o the last during the jacking operation. Preferably the-positioning means will be arran d to center the shoe upon the toe rest be ore the shoe is caused to bear with any consid- As herein shown, the positioning means comprises engaging devices located on opposite sides of the shoe and normally standing away from the shoe to offer no obstruction to the lasting operation. These devices are carried by levers which are arranged to move together toward the shoe and are actuated by a yield: ing connection with a' moving part of the jacking mechanism first toward the shoe to center itv upon the toe rest and then away from the shoe. The yielding connection enables the devices to act satisfactorily upon shoes of diflerent sizes. The engaging devices are arranged to contact with the sides of the shoe as near the toe end as ma be without-getting into the way of the toeasting plates. At this two side faces of the ast are nearly the same distance from the median line of the fore art of the last and the shoe will, therefore,

' e ositioned by them approximately cen-.

ortion of the shoe the ance with a feature of this invention, made the engaging devices adjustable relatively on their carryin levers. As shown, these devices are bloc arran ed to present different acting faces at di er'ent distances from their carrying levers and by suitably. adjusting them lasts having different degree of fullness can be. correctly centered. This invention also. includes an improvement in the toe rest, which is arranged for sliding movement upon its support, against the tension of return springs both lengthwise and transversely of the last, and an improvement in the heel rest, which is mounted to tip laterally to adapt its position to variations in the position and inclination of the pin hole in the last.

The illustrated machine comprises, in accordance with another feature of the invention, means operating inconnection with the mechanism includes a rotary tack-lifti jacking mechanism to arrange and deliver tacks for securing the upper in its overworked or lasted position. The tack arranging, and delivering mechanism comprises, as shown, a hopper or reservoir to contain a mass of tacks and means for lifting tacks in small quantities and so manipulating or handling them as to cause them to become arranged in single line in an inclined raceway by which they are conducted to the tack-driving-mechanism. This mechanism is operatively connected with the actuator for the jacking mechanism to be set into intermittent motion therewith.

It is found in practice that in order to provide a sufiicient supply of tacks the supplying mechanism must continue to run through a considerable period and the best resultsare obtained by operating it slowly. The preferred form of tacksupplyiig 6- Vice for taking tacks from the mass an deositing them upon an arrangin table leading to the raceway. It is foun in practice that the lifting device cannot advantageously be operated .above a certain speed and that it is necessary to continue its actu ation at such desirable speedthrough a longer period than that required for imparting to the jacking mechanlsm its movements, for

positioning and clamping the shoe.

A feature ofthis invention, consists therefore, in interposing between tack-supplying mechanism and the actuator, which is common'toit and to one of the mechanisms for operating on the shoe, herein shown as the jacking mechanism, suitable connections which will cause thetack-supplying mechanism to run after the other mechanism has come to rest. Preferably these connections will be constructed and arran ed to govern the speed at which the supp ying mechanism is operated and as herein shown these connections include a spring arranged to be put under tension by the movement of the actuator and a dash pot operating in a liquid, such as oil, for controllin the rate at which the spring may react and supplying mechanism.

Inthe illustrated embodiment of the in vention the wiper plates of one of the endlasting mechanisms are connected, as has been stated, with the actuator which operates the jacking mechanism and which also run. The fas enings for securing the upper are herein referred to as tacks but other forms of fastenings might be used and the supplying mechanism therefor connected to combinations of pied by. it during the lasting actuate the a mechanism for operating on the shoe in accordance with this feature of the invention. 1

These and other features of the invention including certain details of construction and arts, will be further explained in the ollowing description and pointed out in the claims.

Fig. 11 is a'perspect-ive view of parts shown in Fig. 9. Fig. 12 is a sectional view on line ing mechanism B between which. are located the toe rest 4 and the'heel rest 6. The heellasting mechanism is carried by a plate 3 which. is connected pivotally with the frame by a pin 5. This pivot pin is located under the last and at a point removed from both ends of thelast and at, or approximately at, the point of intersection of the median lines of the heel part and fore part of the last. If desired, the pin 5 may be adjustableas, for example, by providing a slot in the frame, as shown in Fig. 5. By this'means the center about which the heellasting mechanism is movable may be differently positionedrfor lasts in which the point of intersection ofthe median lines is located farther forward or backward in the last. In the movement of the heel-lasting mechanism about the pin 5 the plate 3 slides freely over the frame being supported by rolls as shown in 2*and 3 which' travel ona curved trac andthe-movement. islimited sto s are adjustably mounted upon a right an left threaded screw 9 equidistantfrom the-middle line of the machine. The screw is provided with a crank by which it may be turned for adjusting the .two stops together toward or from the middle of the shoe. These stops serve to limit the lateral movement of the heel-lasting mechanism and when they have been adjusted 'into'the right position for a right last, for example, they I will be correctly located also for. the. left last. .a nd for all lasts of the same style. The heel-lasting'mechanism is provided with a locking device adapted to cooperate with either of thesto s 7. This device comprises.

a-movable bloc 11 having'two hoo or' 13 and operated latches, as shown in Fi the lever 13 for through connections wit the purpose of unhooking it. The lever13 is plvoted to a post 17 which is secured to the plate 3 of the heel-lasting mechanism so that the operator may grasp the lever and the post and by a single movement unfasten .the latch block from the stop and thenmove -to the frame 37 of the toe-lasting mechanism and has screw-threaded engagement with a stationary block '39 on the bed plate for moving the toe-lasting mechanism forwardly andrbackwardly to position it for lasts of different lengths, the toe-rest. being moved lengthwise of the shoe with the toelasting mechanism through its support 28,

see Fig. .4. The carriage 41is herein shown as pivotally. connected at 43, see Figs..1 and 3, with the frame 37 and arranged for lateral movement about, its center by means of the screw 47 provided with a handwheel,

as shown in Fig. 12. The toe-lasting devices are supported on a head which is piv-:

oted at 51 to a carriage 41 and may be adjusted vertically about said. pivot by the screw 53, having the hand wheel 55, as shown in Fig. 12. The lasting devices are carried by asleeve 57, to which is secured a segment 59 engaged by a screw 61 having. a handle 63. By this latter means the toelasting devices may be tipped laterall to adapt them to the lateral inclination 0 the bottom of the shoe.

This movement is effected by connections includingthe links 71 and equalizin lever 73 with an endwise movab e rod 7 to. which is connected the In bearin in the frame 2 there is mounts ed the cam s 'iaft 8 to which is fixed a ratchet wheel 10'engaged by a pawl 12 mounted on a circularly movable pawl carrier 14 and a rod 15 with a-trea'dle 16, shown in ig. 1. An other convenient means may be employe for intermittently actuating the cam shaft either manually or I Mounted upon the shaft 1s a cam 20, shown in Fi 4 and 7, which ena roll on a verticall movable slide 22, guided in the frame and orming a movable support for the toe rest. This rest includes a rod 24 provided with an adjustable screw 26 at its lower end and contacting directl with the slide 22. The rod extends throng a guide 28 and' is grooved to receivea screw which holds it from turning. The rod is provided with a head in which a slide 30 is movable transversely of ,the machine a ainst the pressure of a, spring" 32, shownin. otted lines in Fig. 4. Asecond slide, 34, movable len hwise of the machine and carrying the pa 4, is mounted in the slide 30 and is normally. held in a central s ring 36, also shown in otted -lines. By t is arrangement of the toe rest and its actuating'mechanism the toe pad may'move freely either lengthwise or transversel" of the machine with the last and is raised? lifting the last in. the jacking operation.

' The heel-lasting mechanism, together with the heel support, ismovable lengthwise of the plate 3 rbma retracted position which permits of the convenient insertion of the last to a predetermined operative position which is maintained during the acking and lastinlg operationsyby the hoo .35, carried by t e heel lasting headand for osition by the shown best in Fi .:1, which engages a proe rail of the plate. This hook is mountedon a rock shaft 81carrying at the o 'posite side of the machine an arm 83 whic rests upon a vertically movable rod' 87, see Fig. 4, thatis operated from a cam 89 on the cam shaft 81to release the hook. This takes place as a part-of the unjacking operation after the shoe has been lasted and occurs simultaneously with the opening of the heel band and the depression of the toe support- The heel rest is carried by a slide 40, see Fig. 4, which is lengthwise ofthe machine in the late .3 whlch supports the heel lasting, mec anism and is therefore movable latera 1y pivot 5 with the heel-lasting mechanism.

movable .aboutthebe enga For thispurpose the slide is provided on its" upper facewith rack teeth, which areen ga d bya pinion42 on a shaft44 having a E and wheel 4'5. The hand wheelis pro-' vided on" its inner face with ratchet teeth which are engaged by a spring-pressed awl 46,-as shown in Figs. 2 and 3, to hol the parts in their adjusted sition. A sprin 48 acting against theslldepresses the bee 10 rest forwar ly awav from the heel-lasting mechanism when the pawl 46 is released from the hand wheel. The release of the pawl from the teeth on the hand wheel may e eifected' manuall at any time by means of the lever 49 w ich extends upwardly from the awl into convenient position to ed by the operator. Provisionis also m e in the cam 175, shown'in Figs.

- i 1, 2, and 3, for automatically disen aging the awl from'the hand wheel'and re easing the ack post during the return of the carriage from its last-mg osition. "The cam 175 is fixed upon the p ate 3 inposition to engage by means of its inclined inner face with a lug X de nding from-the pawl 46. The relation of t e parts'when thepawl is held out of engagement with the hand wheel by the cam 175is shown in Fig. 14. A suitable spring, shown at a; or, maybe provided for pressing the pawl toward the hand wheel into position to'engage the teeth when the pawl is moved away from the cam 17 5. The heel post is provided inits lower end 'with an adjusting screw 50 which rests upon a plate 52 connected pivotally to thesllde 40 at 54 and having an inclined face which rests upon the end of a screw 55. This screw is freely movable endwise in the carriage of the heel-lastin .mechanism" and is adjustable in a nut 56, w ichissupported by a spring 58. The screw thus provides a yielding support for the plate 52 and by its engagement with the inclined face of the plate causes the plate to be lifted as theslide 40 and heelpost are moved rearwardly, to draw the last into the heel band of the heellasting mechanism. This'arrangement provides for adjusting the heel post vertically according tothe size of the last inasmuch as the extent of the backward movement of the post into the band will vary according to the distance between the 'pin hole'and the rear end of the last, being less for a large last than for a small one. This engagement of the shoe with the band causes the post to rock or fulcrum about the upper portion of its guide in the slide 40 so that the lower portion of the post, which is toothed as shown in Fig. 4, is forced into engagement with some pawls, the guideway in the slide being somewhat largeratits lower'portion than is the post so that this movement of the post is ermitted.- w

The teet are formed to hold the post,

against downward movement, but ofl'er no I obstacle totheu ward movement of the post; )Whenthepostis tipped out of contact with the awls it is free to move' either upwardly or ownwardly." A rod 60 is arranged below the plate 52 and connected to a treadle 62, shown in Fig. 1, for raising the heel post and the heel end of the shoe or positively upholdin them 'durin the latsting operat1on if esired. The etl post is reduced somewhat in width at its upper end, as

shown. in the sectional view Fig. 6 to permit the post to move lsidewise slightly. Sprin permit some movement of the last thereon and is connected to the post by a ball and socket joint. This provision for the post to move laterally and the pin to move independently'uponthe post enables the heel support to adapt itsv position to'the position and the'inclination of the in hole in 64 hold the post normally in its centra position, The heel pin 65, which enters the pin hole of the last, is tapered to the last. This is an advantage ecause the in holes in lasts are not always accurately ocated, or drilled at the same inclination to the face of the last, and, moreover," in some very crooked lasts the pinhole is located on the right side of the medianlin'e of the heel part of a right last and on the i left side of this median line of av left last. 7 The jackin operation effected by the machine is pro uced by depressing the foot treadle16 after the last with the upper materials assembledon it has been placed upon the heel and toe restsand the heel rest has been moved backwardly by the hand wheel '45 to draw the shoe into the heel band and lock the post against vertical displacement all as above described. This actuation of the treadle turns the cam shaft and causes the cam 20 to raise the toe rest positively as a previously explained, thus forcing the last firmly back into the heel band and clam-ping it rigidly in position to be lasted. The cam shaft also carries a cam 70 which actuates during this jacking operation devices connected with the heel band for closing the band about the sides of the heel portion of the last to force the upper materials, including the heel stiifener, snugly into contact with the sides of the'last. This cam 70, as shown best in Figs. 4 and 7, engages a roll on the lever 72, which is connected by a bar 74 with a lever 75. The bar 74 is formed in j aoiam hism and is.pivotally' connected to'an evener or equalizing bar 85, shown in dotted lines in ends with links 86 to which are pivoted levers 88. The outer ends of these levers are connected; to springs 90, while their inner ends are connected to the front ends of the vheel band. This arrang'ementis such that as the cam 70 is actuated during the jacking 0 eration the rod 84 will be moved forward y and cause the levers 88 to be advanced and rocked for drawing the heel band forwardly and forcing its end portions inwardly against the sides of the shoe, whereby the shoe is clamped laterally in the heel-lasting mechanism by the jacking operriage of the heel-lasting mechanism, and

connected by the rods 102, the. equalizing lever 104, and a slide rod 105 with a lever 106. The lever 106 is fulcrumed on a link 108 attached to a fixed part of the mechanism and is adapted to be actuated manually for advancing and closing the wiper. plates over the shoe bottom at the heel end of the last.

The block 82, above mentioned as being actuated lengthwise of the machine during the jacking operation for closing the heel band, is extended vertically and connected to a rod 110 which is provided at its forward end with links 112 having pin and slot connections with the wiper plate carriers. This arrangement provides that during the j acking operation when the block 82 is advanced for closin the heel clamps the wiper plates will also e advanced and closed. -The arrangement is such that when the wiper plates are retracted and opened prior to re moving a shoe from the machine the pins of the pin and slot connection stand against the rear ends of the slots in the rods 112 so that during1 the jacking operation of the next shoe t e forward movement of the block 82 will cause the links to thrust the plates for} wardly. The momentum of the plates carries them forwardly until they engage the upper at or adjacent to theedge of the heel 0 the shoe. By this means the wiper plates are initially positioned during the jacking operation closeto or sli htly over the edge ofthe last in position or the workman to mani ulate them for forcing the upper into laste position on the shoe bottom. One advantage of this arran ement is that the handle end of the long ever 106, which has a conslderable range of movement, is auto- Fig. 2. This bar is provided at its two matically brought up into position to be conveniently engaged by the workman. The cam shaft 8" carries, in addition to the parts before mentioned, a disk having a projection 120, shown best in Fig. 7, which engages a roll on an angle lever 122, to the upper end of which is connected a yielding plunger 124 pivoted to a swinging arm 125, as shownin said Fig. 7. The arm 125 is connected by three links, the middle .one of which is pivoted to the fixed bracket 135, with a similar arm 126' mounted on the 'o posite side ofthe machine and arranged to e moved by the links with the arm 125 toward and from the last. The

arms are provided with devices for engaging the sides of the shoe for positioning 1t upon the toe rest in the middle of the machine, or in correct operative relation to the toe-lastin devices. This centering of the toe end 0 the shoe forms a part of the jacking operation and the cam 120 is, therefore, located on the cam shaft with relation to the other cams to cause the positioning devices carried by the arms to center the shoe before the shoe is clamped by the heel band.

The positioning devices carried by the arms are herein shown as blocks 128 adapted to fit upon pins projecting from the arms. Each block is provided with a pin hole so located with relation to the sides of the block that the side faces are each a different distance from the pin. A locking device 130 is arranged to'hold the block in its adjusted position. A spring 132 extends from one of the links to an adjusting screw 134 in the stand 135 for holding the positioning devices normally away from the shoe. The

cam projection is so formed that the spring may move the positioning devices away from the shoe immediately after the shoe has been centered upon the toe rest:

The treadle 16, by which the cam shaft is turned for actuating the several jacking means is connected by the link with a rack bar 142, which engages a inion 144. The pinion is mounted on a sha t to which is connected, as shown in Fig. 9, a flanged disk 145. A strong coiled spring 146 is connected at one end to the flange of the disk and at the other end to a fixed portion of the frame at 148 so thatv the spring is wound upand put-under tension when the treadle is depressed for actuating the jacking mechanism. The rack bar 142 is connected to a piston 150 operating in a cylinder 152, having a channel communicating with a receptacle 1.54 adapted to contain a v liquid, such as oil. A screw is arranged to be adjusted for varying the size of'the channel. By this dash 0t arrangement the spring 146 is compelle to unwind slowly and at a rate which can be regulated. The flanged disk,145"carries a awl'156 which is in engagement with a ratc et 158 on a pulley 160. A belt 162 extends from this pul upon a receivin ley to a pulley on the shaft of the rotatable tack hopper 164. The hop er has shelves 163 by which tacks are lifted and deposited plate 165 and fall into a trough 166 lea ing to a raceway 168 by which they are delivered to a removable hand tacking tool 170.

The table 165 is pivotally supported at its rear edge and rests at its front end upon a lever 172, the lower end of which extends under the tacker 170 when the tackerjs in position to receive tacks. WVhen the tacker is removed the Wei ht of the table causes it to tilt downwar ly and throw off the nicks which have accumulated upon it instead of falling'into the trough and race- .way. When the tacker is returned to tack receiving position the lever 172 is "rocked in the direction to restore the table to its normal position.

In the use of the machine the workman selects the shoe to be lasted and according as the shoe is for a right or a left foot, he

usually shifts the heel-lasting mechanism laterally about the pivot 5. He then places the shoe upon the heel rest and runs the heel-lasting mechanism forwardly into its operative position where it is held by the hook 35. The forward portion of the last rests at this time upon the toe support and its end shouldvbe centered between the toe wipers. The angular position of the shoe in the machine is then observed and if it is not such that the toe faces squarely toward the toe-lasting mechanism with the'median line of the forepart of the last coinciding with the median line of the machine, and that the heel-lasting mechanism is symmetrical with relation to the median line of the heel portion of the last, then the lateralthroughout the length of the forepart of the This movement of the last is an an- 1 shoe. gular adjustment laterally about a center at or near the toe, the toe end .of the last be- 7 ing more or less confined between the toe wipers and sustained on the laterally movable toe rest. The adjustment of the heellasting mechanism takes place at the same time with the adjustment of the last and through the same distance as that. of the heel end of the last but its center of movement is at the intersection, at ivot 5, of the median line of the heel part 0 the last with that of the toe part and, because it has the shorter radius of movement said heel lasting mechanism turns through a larger angle than does the last and therefore receives an angular adjustment relatively to the last. This differential adjustment is enough to set the heel-lasting mechanism into symmetrical relation to the median line of the" heel portion of the last. Then by means of the hand wheel 45 the heel post is moved rcarwardly and upwardly for drawing the heel portion of the last firmly into the rear portion of the heel band and to raise the last to present the bottom face of the shoe in the plane of the heel wiper plates. The

operator then depresses the treadle 16 for causing the jacking mechanism and the tack-supplying mechanism to be operated. By this movement of the treadle the spring 146 of the tack-supplying mechanism is wound up and during the jacking operation and subsequent operations connected with.

the lasting of the shoe the spring unwinds, at a rate determined by the adjustment of the dash pot arrangement, for causing tacks to be arranged and delivered to the tacker 170.

The movement of the cam shaft produced by the depression of the treadle is communicated through the cam projection 120 to actuatethe shoe-centering devices for positioning theshoe upon the toe rest. The toe rest is then lifted to tip the shoe backwardly toward and into the heel band and the heel band is closed through motion communicated from the cam to clamp the sides of the last. The. movement communicated from the cam 70 also is transmitted through the. block 82 and rod 110 to the heel wiper plates for advancing those plates up to or slightly over the edge of the last and move the hand lever 106 into position to be conveniently grasped by the operator.

,These jacking operations having been completed, the workman, by means of the hand levers 79 and 106, works the upper over the toe and heel ends of the last into position to be secured.

Usually the foot treadle 62 is employed for raising the last upwardly against the heel plate to compact the overworked upper material against the innersole before it is fastened and the workman also usually employs the double-ended treadle 31 for moving the toe-lasting devices upwardly and downwardly to cause them first to wipe the shoe stock upwardly toward the edge of the last and after the wipers have moved over the last, the head is depressed for causing the wipers to compact the stock on the innersole. The tacking tool 17 0 is then removed from the raceway and used for inserting tacks to secure the upper at the heel portion of the last and sometimes at the toe portion. In lasting welt shoes it is, however, customary to fasten the upper at the toe, portion of the shoe with a binder of continuous material instead of using tacks for the purby the contraction of the spring 80 which pose. When the lasting has been completed the cam shaft is again actuated by the trea dle'16 and the cams turned into a position to unlock the hook 35, thus permitting the heel-lasting mechanism to move rearward I reacts through the lever.76,against the arm n of the lever 75, causin the heel band to open for unclamping the s I .10 ing oe. As the heel-lastmechanism retreats the pawl 46 contacts with the tripping device 175 and is 1; freed from the ratchet'on the hand -wheel 45,

thus'permittingthe spring 48 to force the heel-support and the shoe out of the heel band.- The toe rest is also lowered into its shoe-receiving position, after which the v Workman removes the lasted shoe from the heel and toesupports. In proceeding to- I last. another shoe if it is ,a shoe for the I ment of the heel-lasting mechanism 'fwi I'fthe last is of a somewhat dif-. ferent' style, being more or less crooked, a 25 the toe-lastin same-foot as-th'e one last operated :u'pon and is the same style of last, no lateral adipslt;a
